*Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating only; functional operation of the

device at these or any other conditions outside of those indicated in the operation

sections of this specification is not implied. Exposure to absolute maximum

ratings for extended periods may affect device reliability.

EXPLANATION OF TEST LEVELS

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection.

Although the AD9432 features proprietary ESD protection circuitry, permanent damage may

occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD

precautions are recommended to avoid performance degradation or loss of functionality.
